Abstract

The invention relates to an automatic-driving real-time regulation and control liquid fertilizer jet hole fertilizer applicator. The fertilizer applicator effectively solves the technical problems that a needle body is easy to block and the posture of the needle body cannot be regulated and controlled in real time in the fertilizer application process, and comprises a small crawler-type tractor connected with a machine tool, and the machine tool comprises a rotating rod. A first chain wheel and a second chain wheel are installed at the two ends of the rotating rod, an output shaft is sleeved with a land wheel, the first chain wheel is connected with a first rotating shaft, the first rotating shaft is provided with a first bevel gear, the first bevel gear is meshed with a mechanical speed measuring device, and the mechanical speed measuring device is connected with a fertilizer spraying needle which is connected with an electromagnetic valve, the electromagnetic valve is connected witha liquid fertilizer box, the liquid fertilizer box is connected with a liquid fertilizer pump, and a control box is arranged at the left side of the liquid fertilizer box. The mechanical speed measuring device is used for detecting the operation advancing speed, the fertilizer spraying angle of the fertilizer spraying needle is adjusted in real time through the mechanical speed measuring device, the jet flow angle is basically unchanged in the operation process, the problem that the fertilizer spraying needle is blocked by soil is solved, and the small-area target of fertilizer is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic driving real-time control liquid fertilizer jet hole fertilizer. Background technique [0002] The liquid fertilizer hole fertilization machine is a working tool that applies liquid fertilizer deep to the roots of crops. Existing liquid fertilizer applicators mostly use the traction method combined with fertilizer spraying needles to pierce the holes to realize the deep application of liquid fertilizer. The needle body is easily blocked by the soil during the working process, and it is difficult for the machine tool to adjust the working posture of the fertilizer spraying needle in real time according to the working speed. Small fertilizer area targets cannot be reached, and implements cannot be driven autonomously. [0003] On this basis, the present invention provides an automatic driving real-time control liquid fertilizer injection hole fertilizat...
